git push: fatal: the remote end hung up unexpectedly Connection to github.com closed by remote host

Question

I'm using ssh and RSA keys to access github, but it doesn't work when I push files to the repository.

ykhan21@LENOVO-LEGION:~/repos/homework-1-ykhan21$ git push

How can I fix this?

Answer 1

You can use this question as a reference: Git, fatal: The remote end hung up unexpectedly

• some users face this problem comes due to the buffer settings: e.g. git config ssh.postBuffer 524288000
• you may have misconfigured you remote in the repo (you can check with git remote -v) or the ssh keypair
  • you can to remove the ssh origin and replace it with http
  • you may forgot to add your ssh key to your agent (ssh-add ~/.ssh/id_rsa)
  • you can re-run the steps described in the github documentation https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent
• in other cases, running the garbage collector fixed the issue (git gc)
• you may have missing writing permissions if you created the repository as root (sudo) and git is installed for your user

Answer 2

I found out that the this error usually happens when your files are too big. But my files were not, and I was able to push all of my other projects. Re-cloning into a separate directory helped, but it did not fix the original issue.

Answer 3

I also encountered this issue when trying to push a commit, but I was able to push and pull from my other branches. When I tried again to push on the branch that was having the issue, it was successful.
